First time we spot a Focus ST prototype testing on the Nürburgring. Prototype spotted here features a large, centrally-mounted exhaust.

Here are more spy shots of the upcoming 2012 Ford Focust ST undergoing some testing at the Nürburgring.

This is the first time we see a real prototype on the ring and not a test mule. The prototype is wearing the familiar Kistler RoaDyn wheel force and torque sensors on the wheels.

The Ford Focus ST will get a 2.0 liter turbocharged EcoBoost engine with around 250 PS (184 kW / 246 bhp) and will feature a sport exhaust (perhaps centrally mounted like on this prototype), aluminum wheels and small aero changes to the body.
